WAGON-BODY RAISERr SPECIFICATION forming part of Letters Patent No.651,520, dated June 12, 1900.

Application filed January 31, 1900. Serial No. 3,535. (No model;) I i Too whom it may concern:

Be it known that I, JosIAH StBAvs, a citizen of the United States,residing at Moweaqua, in the county of Shelby and State of Illinois,have invented a new and useful Wagon- BodyRaiser, of which the followingis a specification.

This invention relates to devices for rais ing the bodies of wagons fromthe runninggears, the object of the invention being to provide aconstruction in which the wagon may be moved between parts of the deviceand continued movement of the wagon will act to operate the raiser tolift the body from the gears.

In the drawings forming a portion of this specification, and in whichsimilar numerals of reference designate like and corresponding parts inthe several views, Figure 1 is a perspective view showing the raiserwith the parts in position to hold the wagon-body elevated. Fig. 2 is aside elevation showing the raiser in its lowered position and theposition of a wagon at the moment of engagementwith the raiser tooperate it. Fig. 3 is a view similar to Fig. 2 and showing the positionof the raiser with the wagon-body elevated andthe wagon partly removedtherefrom. Fig. 4 is a detail perspective View showing one of thestop-plates.

Referring now to the drawings, the device of the present inventionincludes a base comprising parallel sills 5 and 6 and cross-braces 7 and8. Upon each sill are fixed two vertical uprights 9 and 10 of equalheight and having a rail 11 mounted upon their upper ends and parallelwith the sill. A link 12 is disposed at each side of the upright 9 andhas its lower end pivotally mounted upon a bolt 13, these links beingall of the same length. Similar links 14 are pivotally mounted upon theupright 10, and between the up per ends of the elements of each pair oflinks 12 and 14 is pivoted a beam 15, the ends of which extend beyondthe links, and which beam is adapted tolie upon the rail 11 at one limitof the pivotal movement of-the links and to lie above and parallel withthe rail at the opposite limit of movement of the links, stops 16 beingprovided upon the rail to determine the last-named limit of movement. Itwill thus be seen that the beams 15, which are carried by the sills 5and 6,may be inde-v 'pendently operated to assume either of thepositions shown in Figs. 2 and 3 of the drawmgs.

Movable stops in the form of plates 20 are connected with the beams 15at one end and upon the inner faces thereof, each of these stops beingin the form of a plate having a longitudinal slot 21, in one wall ofwhich and at one end of the slot is a recess 22. Y These plates areconnected with the beams through the medium of bolts 23, which arepassed through the slots 21 and into the beams, and upon these bolts theplates are slidable and are adapted forpivotal movement. These plateswhen in their operative positions project above the beams 15, and tocause them to assume these positions they are drawn upwardly until thebolts 23 strike the lower ends of the slots 21, and their upper ends arethen rocked in the direction of the adjacent extremities of theirrespective beams to rest against stop-pins 24 and to cause the lowerends of the plates to swing rearwardly and engage the bolts with therecesses 22. When the plates have been moved to this position, the nuts25 upon the bolts 23 may be tightened, if desired, to insure againstdislodgment of the plates, al though it has been found that underordinary circumstances the engagement of the bolts 23 with the recesses22 is sufficient for the purpose.

The present structure is adapted principally for lifting the hay-bodiesfrom the bolsters of the gears, and in practice the wagon is drivenbetween the sills 5 and 6 to move along the sills in the direction ofthe ends adjacent the stop-plates 20, it being of course understood thatthe stop-plates have been previously moved to their operative positions,as illustrated. When the body has reached the proper position above thebeams 15, the forward end of the body strikes against the stop-plates 20and continued movement of the wagon causes the body to press against thestop-plates and move the links 12 and 14 upon their pivots, the momentumgiven to the body being sufficient to cause it to move the beams 15andcarry the links over their dead-centers to rest against the stops 16.As the gears are further moved they pass from the apparatus, leaving thebody in the raised position upon the beams 15. At any subsequent timethe gears may be moved to their proper positions below the body, and thebeams may be lowered to replace the body upon the bolsters.

It will of course be understood that in practice the proportions shownmay be varied and various changes in the details of the structure may bemade and also that anysuitable materials may be employed for the severalparts without departing from the spirit of the invention.

What is claimed is In adevice of the class described, the combin ationwith uprights, of links pivoted thereto, beams pivoted to the links andadapted for movement therewith to lie at different elevations, stopsadapted to hold the links at opposite sides of their centers of gravity,and stops adjustably mounted upon the beams and adapted for engagementby a body to be raised, each of said stops upon the beams comprising aplate having a longitudinal slot and a communicating recess, andapivot-bolt passed through the slot and beam, said plates being adaptedfor movement to cause the bolt to travel in the slots and move into andout of the recesses. V

In testimony that I claim' the foregoing as my own I have hereto affixedmy signature in 30 the presence of two witnesses.
